Research ArticleOpen accessIn the abstractExtraction of Arabic Standard MicromelodyA. Chentir, M. Guerti, D. J. HirstProblem statement: In the early days of speech synthesis research the obvious focus of attention was intelligibility. But many researchers agree that the major remaining obstacle to fully acceptable synthetic speech is that it continues to be insufficiently natural. Approach: In this study, we exploited microvariations of fundamental frequency (F0) of speech (intrinsic and co-intrinsic effects) to extract micromelody effect … …Journal of Computer Science, Vol. 5, Issue 2 · 28 Feb 2009 · 7,291 accessesView PDFCite

Research ArticleOpen accessIn the abstractUnderstanding Information System Failures from the Complexity PerspectiveIndranil MukherjeeProblem Statement: Failure of computer based information systems had been a source of major concern in the modern technological era. Information System (IS) researchers have spent a significant amount of their time and effort in understanding the recurring failure of Information Systems. Studies in this regard have ranged from being primarily technical in their approach to those having a much … …Journal of Social Sciences, Vol. 4, Issue 4 · 31 Dec 2008 · 10,625 accessesView PDFCite
Research ArticleOpen accessIn the abstractPerformance Comparison of Active Queue Management TechniquesT. B. Reddy, A. AhammedCongestion is an important issue which researchers focus on in the Transmission Control Protocol (TCP) network environment. To keep the stability of the whole network, congestion control algorithms have been extensively studied. Queue management method employed by the routers is one of the important issues in the congestion control study. Active Queue Management (AQM) has been proposed as a router-based … …Journal of Computer Science, Vol. 4, Issue 12 · 31 Dec 2008 · 7,201 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Review on Correlations between Fish Freshness and pH during Cold StorageK.A. Abbas, A. Mohamed, B. Jamilah, M. EbrahimianFreshness of fish in most markets was found to be the significant quality parameter. The state of fish freshness was assessed by various methods but most of them were costly, time-consuming and not user friendly tools which made the development of simple, easy, undemanding and reliable system for the evaluation of fish freshness unresolved goal. The findings of many researchers … …American Journal of Biochemistry and Biotechnology, Vol. 4, Issue 4 · 31 Dec 2008 · 11,132 accessesView PDFCite
Research ArticleOpen accessIn the abstractNonlinear Behavior of Single Piles in Jacket Type Offshore Platforms Using Incremental Dynamic AnalysisMohammad Amin Assareh, Behrouz AsgarianThe operation for offshore oil has become an important issue in the recent years.
